AN ENHANCEMENT OF FINITE ELEMENT METHOD WITH MOVING KRIGING SHAPE FUNCTIONS
International Journal of Computational Methods, 2005This paper presents an enhancement of the finite element method (FEM) by adopting the moving Kriging (MK) interpolation as a substitute for the traditional hat functions. The MK shape functions can be referred as element-free because their construction is not tied to the element geometry. Kriging interpolation is a geostatistical technique for spatial

Conformal Based Uncertainty Bands for Predictions in Functional Ordinary Kriging
Functional Ordinary Kriging is the most widley used method to predict a curve at a given spatial point by computing a weighted average of observed functional values in space. Determining the uncertainty associated with predicted curves remains a challenge.Elvira Romano, Romano Elvira

A regularization method for constructing trend function in Kriging model
Structural and Multidisciplinary Optimization, 2018Kriging is a popular surrogate for approximating computationally expensive computer experiments. When sample points are limited, it is difficult to identify the overall trend of the problem at hand properly. Thanks to the interpolating characteristic of the Kriging model, a constant is widely used as the trend function, which neglects the overall trend

Ensemble of Kriging with Multiple Kernel Functions for Engineering Design Optimization
2018We introduce the ensemble of Kriging with multiple kernel functions guided by cross-validation error for creating a robust and accurate surrogate model to handle engineering design problems. By using the ensemble of Kriging models, the resulting ensemble model preserves the uncertainty structure of Kriging, thus, can be further exploited for Bayesian ...

Modeling and Optimization of Functional Response Based on Kriging Model
2016In the continuous complex production process, the value of quality characteristics is not only a single observation value, but a continuous response curve existing in a given space, which named functional response. This paper proposed a quality optimization method for functional response. Firstly, it obtained the sample combines with the uniform design

Functional Decomposition Kriging for Embedding Stochastic Anisotropy Simulations
2017Functional analysis of the kriging algorithm is accomplished with consecutive projections of vectors in Hilbert space. The innovation unveils “functional decomposition kriging” (FDK), which can forecast fields on spatially continuous domains without using blocks, cells, or elements.

Asymptotic Behavior of a Continuous Approximation to the Kriging Weighting Function
2008This technical note contains the detailed arguments of the proof: The main Theorem 4.2 gives conditions on k guaranteeing that the EEC is satisfied and Corollary 4.3 verifies that these conditions are met if k is the Matern covariance under conditions on its parameters.
